regretablly the SFB patches to tc didn't make this release of 'bismark
captown', just the SFB kernel backport to 2.6.37.6.

But as soon as I/someone can either get iproute 2.6.39 ported to openwrt, or
backport those patches from net-next, I look forward very much to trying SFB
in the lab and in some real world scenarios.
